dose control. A set of ALARA recommendations will therefore include both numerical goals and some

relatively general philosophical guidance that, by itself, may not appear to assist in achieving ALARA

goals.

Development and implementation of an ALARA program in many uranium facilities may be a

challenging task, due primarily to the fact that penetrating radiation doses are typically low and few

individuals are exposed near the regulatory limits for occupational exposures. As a result, convincing

management to spend valuable funds to further reduce radiation exposures can be a problem. The ALARA

program must have the support and active participation of all levels of management. It must be understood

by the worker in the field and receive his or her continued support and attention.

Detailed guidance on developing and implementing an effective ALARA Program is provided in

DOE G 441.1-2.

3.2.3 External Dosimetry Program

The details of the external dosimetry program are discussed in Chapter 6 of this Technical Standard and

in DOE G 441.1-4, External Dosimetry Program Guide (DOE 1999f).

3.2.4 Internal Dosimetry Program

The details of the internal dosimetry program are discussed in Chapter 5 of this Technical Standard and in

DOE G 441.1-3, Internal Dosimetry Program Guide (DOE 1999g).

3.2.5 Area Monitoring and Control

The details of the area monitoring program are discussed in Chapters 4 and 5 of this Technical Standard

and in DOE G 441.1-3, DOE G 441.1-4, and DOE G 441.1-8, Air Monitoring Guide (DOE 1999h).

3.2.5.1 Radiological Surveys and Data Trending

Sections 835.401 - 835.403 of 10 CFR 835 establish requirements for radiological monitoring of

areas and individuals. A program of routine, scheduled surveys should be established and followed,

including surveys in areas that are not ordinarily expected to be affected by radiological hazards. The

program should define minimum requirements, survey type, and frequency.

Surveys should be performed at frequencies adequate to identify changes in posting required or

an activity buildup and to ensure current radiological controls are appropriate. The surveys specified by

this section should be considered minimum requirements; additional surveys should be conducted,

recorded, and reviewed as necessary to ensure adequate personnel protection.

Surveys should be performed to identify radiological area boundaries and the conditions within

those boundaries, the appropriate posting of sources or areas, and the location and extent of localized

radiological hazards. They should be performed and documented prior to the start of radiological work,

during general work activities at times when changes in radiological conditions may occur, and following

work to determine that final radiological conditions are acceptable and documented. A sufficient number

of points should be surveyed to adequately assess the radiological status of the area being surveyed.
